(Difluoromethyl)trimethylsilane Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
A direct nucleophilic difluoromethylation reagent. The nucleophilic activation of the silicon center
with Lewis base initiators allows transfer of the difluoromethyl moiety to electrophiles such as
aldehydes, ketones, and aldimines. The copper-mediated difluoromethylation of halides using
TMSCF2H tolerates amine, ether, amide, ester, aromatic bromide, and protected alcohol
functionalities in aryl iodides and occurs in high yield and stereoselectivity with vinyl iodides.
Reaktionen
(1) Direct bromination to prepare TMSCF2Br.
(2) Difluoromethylation of aldehydes and ketones.
(3) Difluoromethylation of aldimines.
(4) Difluoromethylation of aryl and vinyl iodides.
